Beispiele

Im folgenden Beispiel wird veranschaulicht, wie die Stopwatch -Klasse verwendet wird, um die Ausführungszeit für eine Anwendung zu bestimmen.The following example demonstrates how to use the Stopwatch class to determine the execution time for an application.

using System;
using System.Diagnostics;
using System.Threading;
class Program
{
    static void Main(string[] args)
    {
        Stopwatch stopWatch = new Stopwatch();
        stopWatch.Start();
        Thread.Sleep(10000);
        stopWatch.Stop();
        // Get the elapsed time as a TimeSpan value.
        TimeSpan ts = stopWatch.Elapsed;

        // Format and display the TimeSpan value.
        string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}",
            ts.Hours, ts.Minutes, ts.Seconds,
            ts.Milliseconds / 10);
        Console.WriteLine("RunTime " + elapsedTime);
    }
}

Class Program

    Shared Sub Main(ByVal args() As String)
        Dim stopWatch As New Stopwatch()
        stopWatch.Start()
        Thread.Sleep(10000)
        stopWatch.Stop()
        ' Get the elapsed time as a TimeSpan value.
        Dim ts As TimeSpan = stopWatch.Elapsed

        ' Format and display the TimeSpan value.
        Dim elapsedTime As String = String.Format("{0:00}:{1:00}:{2:00}.{3:00}", ts.Hours, ts.Minutes, ts.Seconds, ts.Milliseconds / 10)

Hinweise

Eine Stopwatch -Instanz kann die verstrichene Zeit für ein Intervall oder die Summe der verstrichenen Zeit über mehrere Intervalle hinweg messen.A Stopwatch instance can measure elapsed time for one interval, or the total of elapsed time across multiple intervals. In einem typischen Stopwatch Szenario wird die Start -Methode aufgerufen, schließlich wird die Stop -Methode aufgerufen, und anschließend wird die verstrichene Elapsed Zeit mithilfe der-Eigenschaft überprüft.In a typical Stopwatch scenario, you call the Start method, then eventually call the Stop method, and then you check elapsed time using the Elapsed property.

Eine Stopwatch -Instanz wird entweder ausgeführt oder beendet Stopwatch. IsRunning verwenden Sie, um den aktuellen Zustand eines zu bestimmen.A Stopwatch instance is either running or stopped; use IsRunning to determine the current state of a Stopwatch. Verwenden Start Sie, um mit der Messung der Stop verstrichenen Zeit zu beginnenUse Start to begin measuring elapsed time; use Stop to stop measuring elapsed time. Fragen Sie den verstrichenen Zeitwert Elapsedüber ElapsedMillisecondsdie Eigenschaften ElapsedTicks, oder ab.Query the elapsed time value through the properties Elapsed, ElapsedMilliseconds, or ElapsedTicks. Sie können die verstrichenen Zeiteigenschaften Abfragen, während die Instanz ausgeführt wird oder beendet wird.You can query the elapsed time properties while the instance is running or stopped. Die verstrichenen Zeit werden ständig vergrößert Stopwatch , während der ausgeführt wird. Sie bleiben konstant, wenn die Instanz beendet wird.The elapsed time properties steadily increase while the Stopwatch is running; they remain constant when the instance is stopped.

Standardmäßig ist der verstrichene Zeitwert Stopwatch einer-Instanz mit der Summe aller gemessenen Zeitintervalle gleich.By default, the elapsed time value of a Stopwatch instance equals the total of all measured time intervals. Jeder Aufruf von Start beginnt mit dem zählen der kumulativen verstrichenen Zeit Stop . jeder Aufruf von beendet die aktuelle Intervallmessung und friert den kumulativen Wert für die verstrichene Zeit.Each call to Start begins counting at the cumulative elapsed time; each call to Stop ends the current interval measurement and freezes the cumulative elapsed time value. Verwenden Sie Reset die-Methode, um die kumulierte Zeitspanne Stopwatch in einer vorhandenen Instanz zu löschen.Use the Reset method to clear the cumulative elapsed time in an existing Stopwatch instance.

Die Stopwatch verstrichene Zeit, indem Zeit Geber Ticks im zugrunde liegenden Zeit Geber Mechanismus gezählt werden.The Stopwatch measures elapsed time by counting timer ticks in the underlying timer mechanism. Wenn die installierte Hardware und das Betriebssystem einen Leistungs Bearbeiter mit hoher Auflösung unterstützen Stopwatch , verwendet die Klasse diesen Leistungs Bearbeiter, um die verstrichene Zeit zu messen.If the installed hardware and operating system support a high-resolution performance counter, then the Stopwatch class uses that counter to measure elapsed time. Andernfalls verwendet die Stopwatch -Klasse den systemtimer, um die verstrichene Zeit zu messen.Otherwise, the Stopwatch class uses the system timer to measure elapsed time. Verwenden Sie Frequency die IsHighResolution Felder und, um die Stopwatch Genauigkeit und Auflösung der zeitlichen Steuerung zu bestimmen.Use the Frequency and IsHighResolution fields to determine the precision and resolution of the Stopwatch timing implementation.

Die Stopwatch -Klasse unterstützt die Bearbeitung zeitbezogener Leistungsindikatoren in verwaltetem Code.The Stopwatch class assists the manipulation of timing-related performance counters within managed code. Insbesondere können das Frequency -Feld GetTimestamp und die-Methode anstelle der nicht verwalteten Windows-APIs QueryPerformanceFrequency und QueryPerformanceCounterverwendet werden.Specifically, the Frequency field and GetTimestamp method can be used in place of the unmanaged Windows APIs QueryPerformanceFrequency and QueryPerformanceCounter.

Hinweis

Auf einem Multiprozessorcomputer ist es unerheblich, in welchem Prozessor der Thread ausgeführt wird.On a multiprocessor computer, it does not matter which processor the thread runs on. Aufgrund von Fehlern im BIOS oder der Hardware Abstraktionsschicht (HAL) können Sie jedoch unterschiedliche Zeit Steuerungs Ergebnisse für verschiedene Prozessoren erhalten.However, because of bugs in the BIOS or the Hardware Abstraction Layer (HAL), you can get different timing results on different processors. Um die Prozessor Affinität für einen Thread anzugeben, verwenden ProcessThread.ProcessorAffinity Sie die-Methode.To specify processor affinity for a thread, use the ProcessThread.ProcessorAffinity method.
